Answer:
Pressure = ρgh
pressure (p) is measured in pascals (Pa)
density (ρ) is measured in kilograms per metre cubed (kg/m3)
The fore of gravitational field strength (g) is measured in N/kg or m/s 2
height of column (h) is measured in metres (m)
Answer = 235,200 Pa
Explanation:
Pressure = ρgh
Pressure = 1,000 x 9.8 x 24
Pressure = 235,200 Pa
Answer:
when the ground is very hot and the air is cool.
Explanation:
The hot earth warms a layer of air right above the ground. Light is refracted as it passes through the cool air and onto the hot air sheet (bent). A coating of very warm air near the earth bends the light from the sky almost into a U-shaped bend.
It’s C
solar
correct me if i’m wrong though
Assuming you're working in a 3D cartesian coordinate system, i.e. each point in space has an x, y, and z coordinate, you add up the forces' x/y/z components to find the resultant force.
Answer:
The magnitude of the resultant of the magnetic field is 
Explanation:
Given that,
Current = 40 A
Magnetic field 
Distance = 22 cm
We need to calculate the magnetic field
Using formula of magnetic field
Where, r = distance
I = current
Put the value into the formula
We need to calculate the magnitude of the resultant of the magnetic field
Using formula of resultant
Put the value into the formula
Hence, The magnitude of the resultant of the magnetic field is
